Cairo Being Repainted2

Thank You, Marker Repair Volunteers

IHB staff would like to extend a big thank you to Bruce Cole, his two sons, and the Sigma Phi Epsilon Fraternity at Purdue University for repainting the Cairo Skywatch Tower marker in Tippecanoe County. This marker was installed twenty years ago, and its paint was beginning to chip badly. Thanks to the hard work of these volunteers, the marker is now back in excellent condition!

Is there a state historical marker in your community that you are interested in repainting? If so, please contact us at It’s a wonderful way to volunteer and help preserve the state’s history, especially as we get closer to celebrating our Bicentennial of Statehood next year.


Allison Marker Dedication

Allison Machine Shop Marker Dedicated

On Thursday, May 7, IHB Marker Program Manager Casey Pfeiffer attended the dedication of a new state historical marker commemorating Allison Machine Shop in Speedway. Allison Transmission is celebrating its centennial year, and the marker dedication was part of ongoing efforts to honor the company’s contributions in engineering and manufacturing since its establishment in 1915. Many Allison Transmission employees were in attendance, as well as Lawrence E. Dewey, Chairman, President, and CEO of Allison Transmission, David Lindsey, Council President for the Town of Speedway, and descendants of James Allison.

 IHB would like to thank everyone who helped with this marker! Click here for the marker text, and don’t forget to check back later this summer for the complete footnotes and annotations!

Indian School Marker

American Indian Marker Review Project

We are excited to announce that marker review research has begun on marker topics related to American Indians.  Staff is busy locating primary sources to correct the errors, misconceptions, and distortions made when these markers were originally installed – sometimes as early as the 1940s.  So much new research is available today that we can be sure these marker reports will give a much clearer and more balanced account of these important American Indian histories.
